Let's move the declaration of the "list" variable into the cmd__parse_options() and release it at the end. In c8ba1639165 (parse-options: add OPT_STRING_LIST helper, 2011-06-09) the "list" variable was added, and later on in c8ba1639165 (parse-options: add OPT_STRING_LIST helper, 2011-06-09) the "expect" was added. The "list" variable was last touched in 2721ce21e43 (use string_list initializer consistently, 2016-06-13), but it was still left at the static scope, it's better to move it to the function for consistency.
